What Are Some Common Cable Granulator Machine Malfunctions?

I. Mechanical Malfunctions

1. Worn or Broken Cutters

Symptoms: Incomplete crushing, excessive wire residue, and decreased sorting rate.

Causes: Cutters become dull or damaged after prolonged use; the distance between the moving and stationary cutters is too large.

Solution: Sharpen the cutters every 10 tons of wire processed. Replace them after repeated sharpening as the mesh becomes too narrow.

2. Damaged or Clogged Screen

Symptoms: Incomplete sorting; copper granules and plastic are mixed together.

Causes: Screen mesh is too large or damaged, causing metal and plastic to be screened out together.

Solution: Clean the screen regularly; inspect it every two weeks; replace damaged screens promptly.

3. Worn or Abnormal Noise in Bearings

Symptoms: Unstable machine operation, severe vibration, and a metallic friction sound.

Causes: Bearing wear after prolonged operation, resulting in increased clearance.

Solution: Lubricate the bearings with grease every two weeks, using different types of lubricating oil for summer and winter.

II. Electrical Faults

1. Short Circuit or Open Circuit

Symptoms: Motor does not work, instrument panel does not display.

Causes: Long-term vibration, wear, moisture, or damage from small animals to the wires.

Solution: Check for damaged insulation, loose connections, and replace aging wires promptly.

2. Damaged Electrical Components

Symptoms: Generator, starter, sensors, etc., malfunction.

Causes: Affected by high temperature and humidity, or inherent quality issues.

Solution: Regularly inspect electrical components and replace damaged ones promptly.

III. Operational Faults

1. Machine Jam

Symptoms: Machine suddenly stops running and cannot continue operating.

Causes: Uneven or excessive feeding, loose belt connecting the motor and pulley.

Solution: Strictly control the feeding speed; a feeding frequency of no less than 3 times per minute is generally recommended. Check the belt for looseness and tighten it promptly.

2. Incomplete airflow separation

Symptoms: Copper granules are mixed with plastic, resulting in a decreased separation rate.

Causes: Uneven feeding and unstable operation of the airflow screen.

Solution: Maintain uniform feeding; check the airflow screen for damage or dust blockage at the bottom.
